# Welcome
|
|
|
|
Welcome to the documentation of the THP programming languague.
|
|
|
|
THP is a new programming language that compiles to PHP.
|
|
|
|
## Goals
|
|
|
|
- Bring static typing to PHP: Not just type hints, not use `mixed` for everything
|
|
that isn't a primitive type.
|
|
- Avoid automatic type conversion.
|
|
- Remove the inconsistencies in the language.
|
|
- Organize the stdlib.
|
|
- Differentiate between Arrays, Tuples, Maps and Sets.
|
|
- Create a **consistent** language.
|
|
- Create typings for popular libraries (like TS's `.d.ts`).
|
|
- Have a simple instalation and configuration (requiring just Composer).
|
|
- Ship a fast, native binary (not written in PHP).
|
|
- Sub 10ms watch mode.
|
|
- Support in-place compilation.
|
|
- Emit readable PHP code.
|
|
- Implement a LSP server.
|
|
|
|
|
|
## Not goals
|
|
|
|
These are **not** aspects that THP looks to solve or implement.
|
|
|
|
- Be what TypeScript is for JavaScript (PHP with types).
|
|
- Use PHP syntax/conventions.
|
|
- Be familiar for PHP developers.
|
|
|
|
|
|
## Philosophy
|
|
|
|
- Consistency over familiarity
|
|
- Change over conventions
|
|
- Explicit over implicit
|
|
|
|
That is, while there is value in the items on
|
|
the right, we value the items on the left more.
|
|
|
|

use PDO
|
|
use Globals::Env
|
|
|
|
val (Some(dbUri) Some(dbUser) Some(dbPassword)) = (
|
|
Env::get("DB_URI")
|
|
Env::get("DB_USERNAME")
|
|
Env::get("DB_PASSWORD")
|
|
)
|
|
else {
|
|
die("All 3 db environment variables must be set.")
|
|
}
|
|
|
|
match PDO(dbUri dbUser dbPassword) {
|
|
Ok(connection) -> { /* db operations */ }
|
|
Err(pdoException) -> { /* handle exception */ }
|
|
}
|

```
